Rearview Mirror Mod
by SussyKookie
Rearview Mirror Mod places a configurable rear view inside a box on the HUD, so players can see behind them while moving.
What it does
The mirror is drawn as a HUD box that shows the scene behind the player. Players can toggle it on and off, open a config screen to adjust it, and drag the box to resize it. A Mirror FOV slider changes the angle of the rear camera, which sets how much of the scene the box displays.
The mod is client-only and runs on Fabric for 1.21.11. Only the player's client needs it, so servers and other players can join without installing anything. The source code is public under the MIT License, and the mod is open source.
Key features
Rear view HUD box
A configurable box on the HUD shows what is behind the player, so threats approaching from the back can be spotted without turning around.
Adjustable rear camera
A Mirror FOV slider changes the angle of the rear camera, letting players pick a wider or narrower view.
Resizable mirror
The mirror box can be dragged and resized on screen to fit the HUD layout of each player.
Performance settings
The config screen includes a framerate option for the mirror, the only setting that noticeably changes its cost, since the mirror renders an extra frame before the main one.

Use cases
Watching for pursuers
Players who hear or expect enemies behind them can keep the rear view on the HUD instead of repeatedly turning the camera.
Who it’s for: Players who want a constant view of what is behind them in singleplayer or on a server, and who accept the extra rendering cost of a second frame.
How it compares
World Mirror is also a Fabric, client-side only mirror under the MIT License, but it targets 1.21.11 – 26.3 rather than only 1.21.11. FOV Toggle is client-side only on Fabric as well, with a custom license and a range of 1.21 – 26.3, and it changes the field of view instead of showing a rear view. Rearview Mirror Mod is not a camera toggle; it draws a second view in a HUD box.

What the author says
The mirror allows players to see behind them within a configurable HUD box at all times. No more F5 spamming, no more creepers sneaking up! Because this mod works by calling an extra render before the main render for every frame, it adds a constant multiplier on the complexity. I've tried lowering the resolution and…
